Note: Word limit for each question part is 250 words excluding references, equations and diagrams. a) Assume you are working as a Network Engineer for a Telecommunications service provider and your task is to estimate the feasibility of a 10 km link between two buildings with one access point and one client radio. The access point is connected to an antenna with 10 dBi gain, with a transmitting power of 100 mW and a receive sensitivity of -84 dBm. The client is connected to an antenna with 13 dBi gain, with a transmitting power of 16 dBm and a receive sensitivity of -82 dBm. The cables in both systems are short, with a loss of 2dB at each side at the 2.4 GHz frequency of operation. What is the link margin? By examining the link margin, comment on the reliability of the link. (10 Marks)
b) What recommendation you would make to improve the link margin for the system deployed in part a above?
